S457 – Ureteroureterostomy
OHIP Urology Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
Ureteroureterostomy is a surgical procedure to re-establish continuity of the ureter by re-joining two segments of the same ureter. This procedure is typically performed to repair a damaged or obstructed ureter. As a surgical procedure, it includes pre-operative and post-operative care as defined in the Surgical Preamble and General Preamble. Payment is based on the role of the physician: surgeon (suffix A), assistant (suffix B), or anaesthetist (suffix C).
When to Use
- Use S457 when performing a primary repair of a ureteral stricture or injury by re-anastomosing the two healthy ends of the same ureter.
- Select S457 instead of S453 or S454 when the procedure is specifically a ureteroureterostomy rather than a ureteroneocystostomy or ureteroplasty.
Common Pitfalls
- Billing S457 in conjunction with S482 will trigger an automatic rejection as these procedures are mutually exclusive for the same anatomical site.
- Failing to append the laparoscopy premium E792 when the procedure is performed via a minimally invasive approach results in a significant underpayment of the 25% premium.
Billing Tips
- Always ensure the operative report clearly distinguishes the ureteroureterostomy from any concurrent procedures to avoid audit flags regarding unbundling.
- If a second assistant is required for a complex reconstruction, ensure the surgeon's letter of justification is prepared immediately to facilitate the manual review process required for payment.
